Investing in your community's electricity network

Every two years, we publish a comprehensive asset management plan (AMP) that details our plans for our electricity network areas across the North Island. 

The AMP plots the work we've planned for the next decade to ensure we can continue to deliver safe, secure and reliable electricity to your community now, and to allow for future growth.
